The mventienfdeseribed herein may bemannfactured `and used-by or for the Government for governmental purposes, :without uthe payment tofusof any-royaltythereon.

This .invention relates to a .-mountgfor guns.

It is an Object of 'this invention ,to -sealingly mounta gun for iuniversal movement the wall of acompartment, the Ainterior of which is maintained at a predetermined pressure.

.It is affiirther- Object Ofthis invention te Aprovidea sealed universal mounting for agumwhich will 1permit substantially unrestricted expansion andcontraction of the gun barrel.

It is another object of this v inventionto =sealinglyrmount a kgun in awal1 ,4 with freedom ,'for expansion and-contraction.

It is stillianother object of y.this invention to mount a gun in a wall with freedom for universal movement, with the universal mounting mechanism.:substantially flush with the exterior ofthe wall.

It is yet another object of this invention to provide a universal gun-mounting mechanism in the wall of a compartment in a tank or the like which is sealed for keeping out gas or the like.

Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings, it being clearly understood that the same are by way of illustration and ex,- ample only and are not to be taken as in any way limiting the spirit or scope of this invention. The spirit and scope of this invention is to be limited only by the terms of the appended claims.

In the drawings:

Figure 1 is a part sectional and part elevational View of the mount; and l Figure 2 is a view taken generally along the lines 2-2 of Figure 1 showing an end view of the mount with the gun outlined in the right half and omitted in the left half.

Referring to the drawings, the wall I of a sealed gunners compartment is provided with a circular opening Ia for the reception of ball of the universal mount. Ball 5 is mounted for universal movement in mating plate-like socket members 2 and 3 adapted for bearing engagement with the spherical surface of the ball 5. Members 2 and 3 are bolted together interiorly of, and to, wall l by means of bolts 4 to carry ball 5 with its most forward portion substantially flush with the exterior of wall I. Ball 5 is provided with a cylindrical opening or aperture 6 enlarged to provide a shoulder 1. Received in opening 6 is a bushing 8 having a flanged portion adapted.- to abut shoulder 1. Ball 5 isfinteriorly' threaded at II to receive a correspondingly threaded gunfcarrying packing `gland I0- The forward end of gland I0 fengagespacking element 9 and forces -it finto sealing y engagement with the flangedRportion 8atof member 8 and also with gun'barrel 2|. Gun bar-rel 2l is ,otherwise receivedl in spaced relation in opening :6, gland I0 andbushing 8 with freedom for unrestricted .expansion and contraction. This spacedfrela- `tion ofthe barrel A obviatesbinding of thenbarvrel and accompanying inaccuracies of the gun. Packing gland I0 is provided With a pairI of"v rearwardly .projecting'lugs I2 and I3, ylug I2 of-which isprovided with ,a recessed opening I4 and a bolt-receivingopeningI5. Lug I3 is .provided withorresponding openings I6 and Il. `Gun 20 isjfastened t0 lugs ,-IZ and I3 to be carriedthereby by .stud, screws... I 8 received-r in recessed openings Il and I6, andjbolt ,I9 received in openings I5 and- I1. The opening 6 vin ball 5 is made sufliciently large to accommodate different sized gun barrels. In order to properly position the packing 9, the member 8 constituting a bushing or shim means is provided. As shown in Figure 1 of the drawings, the inner diameter of the member 8 is but slightly larger than the gun barrel 2I. Similarly the internal diameter of the packing gland I0 is of substantially the same internal diameter as the member 8. Therefore, when packing gland I0 is screwed into position the packing will be compressed and held firmly in sealing position against the barrel of the gun. Obviously the internal diameters of members 8 and I0 may be varied to accommodate gun barrels of different diameters.

In order to effectively seal socket member 2 with respect to wall I, a sealing member 22 is .provided therebetween.

Movement of ball 5 in socket members 2 and 3 is facilitated by a suitable lubricant applied to the respective bearing surfaces through lubricant tting 23. The lubricant also provides a seal be.- tween the ball and the socket elements.

Ball 5 is provided with openings 24 for the reception of a spanner'wrench to aid in tightening packing gland I0.

It is to be understood that various modiiica.- tions may be made in the details of apparatus without departing from the spirit or scope ofthe invention, it being intended to be limited onl by the appended claims.

We claim:

1. A, mount comprising a wall of a sealed com--` partaient, saidl wall having an aperture therein,

socket means sealingly attached to said wall with the longitudinal axis thereof in substantial alignment With said aperture, ball means received in said socket means, said ball means being provided With an aperture, an adapter having lug portions and a tubular portion, means detachably connecting said adapter to said ball= means, means connecting a gun to said lug portions with the gun barrel received in and spaced from the aperture in said ball means, and sealing means btween said gun barrel and said ball means,1said tubular portion of said adapterconstituting seal positioning means.

2. A mount comprising a Wall of a sealedcomw-A partment, said Wall having -an 'aperture-therein,

means between said gun and said ball means, and an adapter for connecting said gun to said ball means and for operatively positioning said sealing means.

5. A mount comprising a wall of a sealed compartment, said wall having an aperture therein, socket means sealingly attached to said Wall with the longitudinal axis of the socket means in substantial alignment with said aperture, ball means operatively received in said socket means with freedom for universal movement, said `ball means being provided with an aperture for loosely receiving 'the barrel of said gun, sealing means'between said barrel and said ball means.

socket means sealingly attached interiorly of said Wall and adjacent said aperture, apertured ball means received in said sooket rmeans withthe front of said ball substantially flush `with the ex- 'I teror of said wall, a gun carried by said ball means with the gun barrel received in and spaced from the wallsdening the aperture in said-ball partmena said Wall having an aperture therein,

socket means sealingly attached to said Wall with the periphery of said socket means adjacent th'e periphery of said aperture, ball means received in said socket means with freedom for universal movement, said ball means being provided with an aperture for loosely receiving a' gun, sealing and an `adapter for connecting said gun to said ball means, said adapter including means for positioning said sealing means.

e 6. A sealed universal mount comprising socket )means adapted to be sealingly mounted in alignment with an opening in a wall of a sealed compartment, ball means mounted in said -socket -means With freedom for universal movement therein, said ball means being provided with an aperture therethrough for receiving a gun barrel in spaced relation thereto, said aperture being of 'an enlarged diameter for a portion of its length to form a shoulder, a bushing abutting said shoulder and having an internal diameter slightly greater than the external diameter of said gun barrel,- packing means positioned against said bushing and in engagement with said barrel, a

packing gland for holding said packing in engagement With said bushing and barrel including va tubular portion having an internal diameter but slightly greater than the exterior diameter `of said gun barrel and means on said packing gland for supportingly engaging of said gun.
